8 questions

Decimals or fractions are accepted for numeric answers. Proofs and written responses use sample answers and require human marking. This is practice, not a protected examination.

1 Which term best matches this description: A Boolean test used to choose whether a block runs.

Show answer and explanation

Condition

Condition is the matching concept in this lesson.

2 Which term best matches this description: One possible path selected by a conditional.

Show answer and explanation

Branch

Branch is the matching concept in this lesson.

3 Which concept would you apply first in a situation where a structure that repeats a block according to a rule.

Show answer and explanation

Loop

The scenario directly calls for Loop.

4 Name the concept described as: One pass through a repeating loop body.

Show answer and explanation

Iteration

The intended concept is Iteration.

5 Which statement about Condition is most accurate?

Show answer and explanation

A Boolean test used to choose whether a block runs.

The definition in the lesson notes gives the required condition.

6 Explain one important difference between Condition and Branch.

Sample answer and marking guidance

Condition: A Boolean test used to choose whether a block runs. Branch: One possible path selected by a conditional.

Credit a clear distinction using both definitions and an appropriate example if supplied.

7 Give a short example showing how Loop would be used in practice.

Sample answer and marking guidance

A valid example should demonstrate this idea: A structure that repeats a block according to a rule.

Credit a relevant scenario that applies the concept rather than merely naming it.

8 Summarize why Iteration matters in the lesson “Conditionals and loops”.

Sample answer and marking guidance

Iteration matters because One pass through a repeating loop body.

Credit the core purpose, scope and any important limitation from the notes.
